High Tear, High Efficiency – The IOTA-HTV 313 Series for Demanding Molding Lines
In today’s competitive molding industry, material choice directly impacts part quality, production speed, and total cost. The IOTA-HTV 313 Series high tear silicone rubber is engineered to elevate all three. Developed for applications requiring superior physical strength—such as electronic accessories, industrial seals, and lifestyle products—this series delivers consistent performance shot after shot.
The product line covers a broad hardness range (25A to 70A), allowing designers to select the optimal durometer without changing material families. This simplifies inventory management and process optimization. Typical physical properties include tensile strength up to 8 MPa, tear strength up to 30 kN/m, and elongation from 400% to 850%, depending on grade. These figures are obtained using a standard 1.0% bis(2,4-dichlorobenzoyl) peroxide cure at 175°C for 5 minutes, ensuring reproducible results in actual production settings.
One of the standout features of this series is its excellent mold release behavior. Reduced sticking means fewer rejects, less mold fouling, and shorter cleaning intervals—all contributing to higher overall equipment effectiveness (OEE). Combined with good flow characteristics and stable plasticity, the material supports both compression and transfer molding processes with ease.
Safety and compliance are built into every batch. The IOTA-HTV 313 Series meets ROHS, REACH, and FDA criteria, giving you confidence for export-oriented manufacturing and consumer-sensitive products. The 20 kg carton packaging is convenient for handling and storage, and the 18-month shelf life (under 50°C unopened) ensures long-term usability.
Whether you are producing high-volume consumer goods or specialty industrial components, this silicone series offers a dependable balance of tear strength, flexibility, and curing speed. Its proven track record in high-intensity molding applications makes it a smart choice for factories aiming to reduce waste and improve output quality.
